Barcelona coach Luis Enrique says the thought of having a team without Lionel Messi is "not even something we contemplate".

The future of the Argentina forward as been the subject of much speculation recently, following reports that he had fallen out with Enrique.

Messi has been linked with a move to Barclays Premier League champions Manchester City and leaders Chelsea, but Enrique does not want to see the four-time former world player of the year leave the Nou Camp.

I don't know what the future holds for us. We all think that Messi will be at Barca in the next few years and that is what all the cules (Barca fans) want.

The thought of having a team without Messi is not even something we contemplate.

Spanish side Valencia say they will ban the fan who hit Leo Messi with a bottle during their match with Barcelona on Sunday.

The Argentine forward was struck when celebrating Sergio Busquets' last-minute winner over Valencia at their Mestalla stadium.

"Valencia CF regret and condemn the isolated incident in the game against FC Barcelona, in which a small, uncapped bottle of water was thrown from the stands at opposition player Lionel Messi," Valencia said on their website.

"The club will endeavour to locate the person who threw the bottle and they will be banned for life from the Mestalla.

"Valencia CF operate a zero tolerance policy on such actions and rigorously enforce all security measures set out by legislation."
